Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal packing machine, metal packing block, and specifically relates to a metal packing block, a pressing mold, a pressing device and a method. BACKGROUND

[0002] In order to improve the scrap steel ratio in the steel production process, Professor Chen Linquan theoretically calculates and analyzes the melting of scrap steel in molten iron and molten steel, and carries out field verification. The melting process of scrap steel in molten iron is usually at a temperature of 1250-1500 DEG C, and the melting point of scrap steel is above 1500 DEG C. Because the melting point of scrap steel is higher than the temperature of molten iron, according to the thermodynamic model and test of scrap steel melting, the melting process of scrap steel in molten iron is as follows: in the initial melting stage, the temperature difference between scrap steel and molten iron is large, and the molten iron solidifies on the surface of the scrap steel to form a solidified layer; with the extension of time, the temperature of the scrap steel rises, and the solidified layer on the surface begins to melt; carbon in the molten iron mass transfers to the surface of the scrap steel to form a carburized layer; the temperature of the scrap steel continues to rise, the carbon content on the surface of the scrap steel increases, and the melting point decreases; when the melting point of the carburized layer on the surface of the scrap steel is lower than the temperature of the molten pool, the scrap steel melts to form a liquid state. Then the surface of the scrap steel repeats solidification -> carburization -> melting until the scrap steel is completely melted. Therefore, the limiting link of the melting of scrap steel in molten iron is the mass transfer of carbon on the surface of the scrap steel.

[0003] The scrap steel is made into a packing block, which is convenient for storage, transportation and charging for recycling, and the loss is extremely low, which is an effective way of scrap steel processing, but the scrap steel packing block has a large volume and is compact inside, which is not conducive to heat transfer, mass transfer, conduction, convection and radiation, and is also not conducive to observing the composition inside the scrap steel.

[0004] Currently, there is a method of adding fuel in the converter, but when the scrap steel is smelted, the fuel will directly float to the surface of the molten steel, which cannot fully contact and heat the scrap steel, thereby reducing the smelting efficiency of the scrap steel.

[0005] The present application is directed to the improvement of the existing process, and provides a metal packing block, a pressing mold, a pressing device and a method, so as to improve the technical effect of the use efficiency of the scrap steel block. SUMMARY

[0006] (I) Technical problems solved

[0007] In view of the deficiencies of the prior art, the present application provides a metal packing block, a pressing mold, a pressing device and a method, which solve the following technical problems:

[0008] 1. The scrap steel packing block has a large volume and is compact inside, which is not conducive to heat transfer, conduction, convection and radiation;

[0009] 2. The scrap steel packing block has a large volume and is compact inside, which is not conducive to observing the internal composition;

[0010] 3. Adding fuel directly to the converter will cause the fuel to float directly to the surface of the molten steel, which will prevent the fuel from fully contacting the scrap steel and generating heat.

[0138] Example 11: another pressing method using double-sided die

[0139] A pressing method of a metallic packing block, including scrap steel and the pressing equipment in example 10, the end of the longitudinal pressure block 52 is provided with a magnetic chuck, including the following steps:

[0140] Step one C: put the scrap steel into the packing groove 51;

[0141] Step two C: start the pressure plate hydraulic cylinder 531 to make the pressure plate 53 press to the horizontal, and make the partition plate 61 contact with the bottom of the packing groove 51;

[0142] Step three C: start the cross pressure block hydraulic cylinder 541 to make the cross pressure block 54 press to the left end of the inner wall of the packing groove 51;

[0143] Step four C: start the two longitudinal pressing block hydraulic cylinders 521 to press the scrap steel in the corresponding direction of movement;

[0144] Step five C: start the magnetic chuck and the two longitudinal pressing block hydraulic cylinders 521 to pull the pressed semi-metallic baling block 1 away from the partition plate 61;

[0145] Step six C: close the magnetic chuck and start the pressing plate hydraulic cylinder 531 to make the pressing plate 53 perpendicular to the bottom of the baling slot 51, and start the rotating motor to make the double-sided mold 4 on the pressing surface of the pressing plate 53;

[0146] Step seven C: start the pressing plate hydraulic cylinder 531 to make the pressing plate 53 press to the horizontal and make the double-sided mold 4 contact with the bottom of the baling slot 51;

[0147] Step eight C: start the longitudinal pressing block hydraulic cylinder 521 to press the scrap steel in the corresponding direction of movement;

[0148] Step nine C: start the magnetic chuck and the two longitudinal pressing block hydraulic cylinders 521 to pull the pressed semi-metallic baling block 1 away from the double-sided mold 4;

[0149] Step ten C: close the magnetic chuck and start the pressing plate hydraulic cylinder 531 to make the pressing plate 53 perpendicular to the bottom of the baling slot 51;

[0150] Step eleven C: start the longitudinal pressing block hydraulic cylinder 521 to press the two pressed semi-metallic baling blocks 1 into a metallic baling block;

[0151] Step twelve C: take out the metallic baling block and complete the pressing.

[0152] In addition, the person skilled in the art should pay attention to the following points when using the device in the above embodiment:

[0153] In the embodiment, the scrap steel is pressed twice, so the loading force of the longitudinal pressing block 52 needs to be controlled properly during the first pressing, and the maximum loading force is preferably less than 50%, and the maximum loading force is greater than 50% during the last pressing.

[0154] Since the mold is arranged at the end of the pressing surface of the lower pressing plate 53, part of the mold will be blocked by the inner wall of the baling slot 51 when the lower pressing plate 53 rotates, so a certain arc (such as Figure 22 ) can be arranged on the inner wall of the baling slot 51, and the center of the arc surface of the arc coincides with the axis of the rotating shaft of the lower pressing plate 53, which facilitates the rotation of the mold.

[0155] Because the mold has protruding surface, in order to prevent the mold from being worn, the lower hardness scrap steel can be selected to be pressed.

[0156] In order to fix the lower pressing plate 53 and the packing groove 51, the locking rod 533 is arranged at the end of the lower pressing plate, and the locking hole 511 is arranged at the corresponding position of the packing groove 51.

[0157] In the embodiment 11, because the scrap steel is pressed for many times, in the first two times of pressing, the loading force of the longitudinal pressing block 52 needs to be controlled, and preferably, the maximum loading force of 50% to 30% is selected, and in the last time of pressing, the maximum loading force greater than 50% is selected.

[0158] In the scheme of adopting the double longitudinal pressing block 52 and the double-sided mold 4, the loading forces of the two longitudinal pressing blocks 52 can be the same, but because the amounts of scrap steel on the two sides of the double-sided mold 4 are not necessarily the same, the deformation degrees of the scrap steel on the two sides are different, thereby causing the double-sided mold 4 to be excessively pressed by the scrap steel on one side. Therefore, the mold guide rail 534 can be arranged on the lower pressing surface of the pressing plate 53 to be connected with the double-sided mold 4 (as shown in Figure 23 ), so as to prevent the deformation degrees of the scrap steel on the two sides of the double-sided mold 4 from causing the double-sided mold 4 to be excessively pressed by the scrap steel on one side. In the scheme of adopting the rotating plate 6, the similar rail connection mode can also be adopted to reduce the excessive pressing of the double-sided mold 4 by the scrap steel due to the different deformation degrees.

[0159] If the installation groove 11 and the installation block 12 cannot connect the two half metal packing blocks 1 firmly (to prevent the structure from being disassembled in the subsequent transportation process) after pressing, a layer of glue can be applied to the installation groove 11, the installation block 12 or the surface to be connected before pressing to facilitate the connection. In the case of being difficult to combine, the two half metal packing blocks 1 can also be combined into a metal packing block by welding or spot welding.

[0160] The way of adding coke in the blind hole in the embodiment 7, the embodiment 9 and the embodiment 11 can be manual addition or addition by the feeder. If the feeder is adopted for addition, the metering scale can be arranged at the bottom of the packing groove 51, and the corresponding type (silicon, coal, etc.), quality of fuel is added according to the mass ratio of the metal packing block added in the future smelting scrap steel and the demand of the final smelting steel.

[0161] The following table is the comparison of the time and the number of equipment for pressing one metal packing block in the embodiment 7, the embodiment 9 and the embodiment 11.

[0162]

[0163] The cost of the equipment modification in embodiment 7 is the lowest and the requirement for materials is also low, only the longitudinal pressing block of a common metal packing machine needs to be modified, but a common metal packing machine is also needed to press the two half metal packing blocks 1 again, and the half metal packing blocks 1 need to be transported for many times in the process, so the time is long.

[0164] Embodiment 9 is the fastest metal packing method, but the requirement for the material of the mold is high, and the mold is easy to be squeezed and damaged, so the pressing cost is not necessarily lower than that of embodiment 7 from the long-term operation or the initial construction, but if the mold has a breakthrough in the material, it is undoubtedly the best pressing scheme.

[0165] Embodiment 11 is an improvement of embodiment 9, which aims to reduce the requirement for the material of the mold, although the half metal packing block 1 is also pressed three times, but the transportation process is reduced, and a metal packing machine can complete the pressing, so embodiment 11 is the best pressing scheme of the metal packing block at present.

[0166] In summary, the metal packing block and the pressing mold, the pressing equipment and the method, a new metal packing block structure is designed, which includes a closed hole and a through hole, fuel can be added in the closed hole, the molten steel amount required for the scrap steel smelting is reduced, the smelting ratio of the scrap steel is improved to provide heat, and because the fuel is added in the closed hole, the fuel will not float on the surface of the molten steel because of being added into the molten steel, in addition, the through hole can be used to observe the internal composition of the packing block, and the molten steel and airflow can flow through the through hole during the scrap steel smelting process to accelerate the smelting of the scrap steel.
